My observation has been that most people pay a lot of attention to their personal preferences. Whether an individual also pays attention to facts which might contradict one's opinion is somewhat less common. Use something that suits your requirements. > Is it fair to say the comparisons are between: Sendmail, Qmail, Postfix and Courier? Sure, if those are the ones you want to consider. For me, I've never heard or Courier....so my definition of "fair" would be different. Have you heard of zmail, smail, smtpd, or even a product called Communigate Pro? [ The latter might provide an integrated solution along the lines you've been asking about and decent tech support, which might be closer to what you want. No connection, but some people I've worked with had liked their product. ] > For 3 - 5,000 (or more) users, requiring POP3 & IMAP & web messaging, > what have people found to be their favorite and most reliable MTA? I've been running sendmail for ~14 years, with up to 22,000 users in one case; but someone else can undoubtedly say the same for the other programs. For instance, I had a conversation about the utility of multiple queue runners and so forth (now in sendmail-8.12) who was using postfix to do around 3 million messages a day...but he didn't want or need some of the features that sendmail provides. Something like UWash IMAP or AMS-2/Cyrus + MailMan + squirrelmail would probably be my route for the non-MTA aspect of your question. If you want to be proactive about security, make sure to link with SSL to provide STARTTLS and secure versions of the IMAP/POP3 protocols. Perhaps you should also consider your backup situation, hardware details like amount of disk storage and system capacity growth you plan for, getting hot-swappable SCSI or fibre-channel disks, things like that.... -Chuck To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
